Title: Pre-treatment method of sintering material
Inventor: SAIKI GOROU
IPC: C22B1/16
Filed: 1981-04-17
Abstract: PURPOSE: To obtain a granulated substance which is high in its gas permeability and strength, by performing a heating treatment to a sintering material constituted of specific grain size mixed in advance, and granulating it by a granulating machine.  
     CONSTITUTION: A sintering material whose grain size constitution mixed in advance is -7mm≥80wt%. 10W30wt% -125μ, and 1W3.5mm average grain diameter is led into a mixing and kneading machine, and a heating treatment is performed. As a result, fine powderIcovers intermediate grain II and rough grain III, adso water content is scarcely required, and adhesive force of the intermediate grain II and the rough grain III is elevated. Also, it becomes possible to make the intermediate grain II showing a pseudo granulating property adhere to the rough grain III. The sintering material to which this heating treatment has been performed is granulated by use of a drum mixer, a pan pelletizer, etc. in the next process.

Title: Video signal converter
Inventor: TAGAMI TOMOHISA
IPC: H04N5/92
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To prevent the level shift of signal caused by an offset voltage or the level shift of input signal at the time of conversion concerning a video signal converter for digital or analog conversion. SOLUTION: When inputting an analog video signal to a 1st A/D converter 2 and converting that signal into a digital video signal, a digital pedestal level detection part 3 detects the pedestal level of digital output signal. This pedestal level is applied through a D/A converter 4 for reference correction to a 1st control part 5. Corresponding to the pedestal level, the 1st control part 5 prepares upside and downside reference voltages and supplies them to the reference voltage input terminal of the 1st A/D converter 2. Thus, even when the conversion offset voltage or the like is generated and the pedestal level of the output signal is shifted, a DC level is always fixed through feedback control and the high-accuracy digital video signal can be provided.

Title: Memory access control system
Inventor: SUZUKI SATORU
IPC: G06F12/00
Filed: 1990-03-09
Abstract: PURPOSE:To attain an effective access to a memory by permitting the other one of both memory access devices to perform a memory access in a permission reception system and in the timing where the same other memory access device owns the priority. CONSTITUTION:The priority access right to be given to the memory devices 1 and 2 are given alternately to the memory access devices 3 and 4. The memory access permission arbitrating circuits 32 and 42 set the memory access permission registers 31 and 41 only when its own memory access device has no memory access in a cycle where a memory access request signal is inputted from the other one of both memory access devices and then suppress the memory access of its own device in the next memory cycle. Then the outputs of both registers 31 and 41 are inputted to the memory access control circuits 33 and 43 of the other memory access device as the memory access permission signals. As a result, the memory access is possible when the access timing of the other memory access device is not busy. Then the transfer efficiency is improved.

Title: Pretreatment method for sludge dehydration
Inventor: NAKANO ICHIROU
IPC: C02F11/14
Filed: 1978-05-15
Abstract: PURPOSE: To enhance the size the rigidity of flocs and to improve dehydration ratio of sludge by admixing an acid, oxidizer, and flocculant to sludge for pretreatment before dehydration.  
     CONSTITUTION: The sludge formed by draining treatment of sewage, urine, and the like is stored in a sludge storage tank 1, and then subjected to pretreatment in which the sludge is added with a strong acid 5 such as sulfuric acid in a first mixing tank 2 and then with chemicals 6 (an oxidizer such as hydrogen peroxide and an inorganic flocculant such as a calcium salt) in a second mixing tank 3. The oxidizer oxidizes and decomposes organic substances in the sludge; the acid adjusts the pH of the sludge, lowers the potential of hydrophilic sol, and improves the flocculation function of the flocculant. When dehydration is conducted in a dehydrator 4, the sludge is dehydrated well and the amount of cake formed is reduced because the flocs are large in size and rigid due to the function of the chemicals 6 added.

The layer 3 is required to have not only an electric charge generating function but also a function of being changed from a hydrophobic state at the time of forming an electrostatic latent image to a hydrophilic state at the time of printing. The reaction product of a crosslinking agent and a resin having an aicd anhydride ring structure, per se, is hydrophobic and has sufficient resistance for holding the latent image, but when it is treated when an alkaline aqueous solution, the acid anhydride ring part is opened by water to provide hydrophilic nature, which enables printing. Since the surface of the layer 3 becomes hydrophic but not water-soluble and has sufficient water resistance, durability in printing can be obtained.
